(a) Find the speed of the particle at time t = 4s.


(b) Find the acceleration of the particle and the force applied to it that causes this motion as functions of t.


4<br>At time t = 0, an object (modelled as a particle) of mass 16 kg is at the point P =<br>-8<br>3<br>measured in metres. It is travelling with velocity<br>-E)-<br>cos(3t)<br>v(t) =<br>-5t<br>ms-!.<br>-4(t+2)-2<br>

Extracted text: 4 At time t = 0, an object (modelled as a particle) of mass 16 kg is at the point P = -8 3 measured in metres. It is travelling with velocity -E)- cos(3t) v(t) = -5t ms-!. -4(t+2)-2
